Long-term rental The property is currently listed at €674,000, which is significantly above its fair value of €556,209, indicating it is overpriced by 17.5%. Given the gross yield of 5.5%, potential returns are undermined by the initial overvaluation, making it a less attractive long-term investment. Family rental While the suburban location offers a generally low crime environment and decent neighborhood rating of 75/100, the property’s listing price of €674,000 is not reflective of the fair value of €556,209, rendering it overpriced. The 5.5% gross yield may appeal to families, but the excessive price diminishes the investment's attractiveness to potential renters seeking value. Buy-and-hold At a listing price of €674,000, the property falls short of fair value at €556,209, highlighting a 17.5% overpricing issue that clouds its long-term appreciation potential. The combination of a 5.5% gross yield and the property’s condition rating of 77/100 suggests that while it may hold some value, the initial investment remains too steep for a sound buy-and-hold strategy.
Tenant Turnover Risk Given the Tenant Stability score of 70/100, there is a risk of higher turnover rates, which can lead to increased vacancy periods and additional leasing costs.
